Actually, I'm trying to keep some memories of Pascal. In Pascal you write:

var
  age: integer;

The family of languages derived from C is already doing enough to keep
the ALGOL tradition alive.

Anyways, "age: int" matches what you write in function signatures in
Python, so I think our hands are tied here and we might as well make
the most of it.
